# Auth Agent

> OAuth 2.1 Authentication for AI Agents

## Welcome to Auth Agent

Auth Agent is a secure OAuth 2.1 authentication system designed specifically for AI agents. It enables websites to safely authenticate and authorize AI agents while giving users full control over their agent's permissions and identity.

## Integration Scenarios

Auth Agent supports three distinct integration patterns to meet different use cases:

### 1. Full Account Access

The agent operates within the user's existing account with full access to their data and context.

### 2. Contextual Profile

The website creates a separate agent profile but provides access to the user's context and data.

### 3. Fresh Profile

The website creates a completely fresh agent profile with no access to user context.
